Hi,
I'm working with a fairly old Marlin setup and want to use M42 to switch some pins.
In the Code documentation there is a line saying "Set the pin mode. Prior to Marlin 2.0.9.4 this is set with the M parameter." I've been trying to find some documentation on this, but unfortunately can't.
Does anyone know the correct usage of M42 and M-value in Marlin 1.1.x.
Many thanks,
Ingo
